Ring is an Amazon-owned brand, so it’s no surprise that their products are featured with some of the deepest markdowns of Prime Day. Whether you need the camera stand-alone or as part of a bundle, you can expect to save up to half off the regular price.

The Oura Ring 4 is our choice as the best smart ring, and its Brushed Silver variant is on sale for the first time during Amazon's Prime Day at 15% off.

In honor of Prime Day, Amazon is going against the norm with the first-ever price cut on Oura Ring 4: With a 15% reduction on all sizes, you can now buy the Oura Ring 4 in silver, size 10, for $297 from $349. Other sizes are also on sale, but some of them are already sold out.
